Import Image with Drag and Drop as Plane
To import a lot of images at once ... it is much faster to use included addon Images as Planes, just enable it in User Preferences. Addon imports multiple images, you can set a basic material and set distance between images to bring them organised
Note - by drag&amp;drop you import only one image per drag, then you will have to convert Empties to Planes (as pointed by Jachym Michal)
